Please keep in mind that I know nothing about Matlab.
Matlab Builder JA lets developer build Matlab applications and export them into Java jars. That\'s great, I just ha
MATLAB Builder JA for Java is currently £3,150 for an individual commercial license, and requires MATLAB Compiler, which is currently £3,850 for an individual commercial license. I'm in the UK so can't get pricing in other currencies, but you can get your local prices from the following links.

Contrary to Birdasaur's answer, the products (and the deployed components) are not supported on Solaris - MATLAB itself has not been supported on Solaris since R2010a. You can also deploy the generated .jar files to as many sites as you like. Individual licenses can be either assigned to a named individual, in which case only that developer can use the product; or to a specific machine, in which case any developer can use it as long as they are at the console of the machine (not remotely logged in).
MATLAB also has an undocumented interface called JMI (Java MATLAB interface) that you can use to call MATLAB directly from Java. Take a look at matlabcontrol. However, this requires a live copy of MATLAB for the deployed application.
